The Haida 100mm filter system involves the use of a dedicated 100mm filter holder, which connects to the lens via a compatible adapter ring.
The 100mm filter system can be preferred for easy compatibility with a wide range of lens sizes, as well as the flexibility offered by mixing and matching different filter types (square 100x100mm, rectangular 100x150mm, and dedicated circular filters).
For example, the 100x150mm Graduated ND filter can be adjusted by moving the filter up or down within the holder to change where the graduation line falls in the image, which is not possible with a traditional circular filter.
